Seems silly to me, if it's a bay, there's silt flowing into it, time itself could pile 10cm of detritus into the deepest parts and make it more shallow.
Or currents might deepen a hole too. Putting silt in one place can cause other places to change too.
And if it were more shallow, shipping would have a big impact too.
